One directory is OK with me. util/gen_acpi or something like that.
However, the approach to have every possible acpi-related function in 
one binary is definitely a non-starter for me. Remember the Unix style 
of small tools doing small things? sed and grep are definitely related, 
but nobody (except maybe busybox folks) would argue to have them in one 
binary. In fact, sed and grep functionality is overlapping more than 
genfadt and gendsdt.
Then again, having "stringtool --grep", "stringtool --sed" and 
"stringtool --cut" instead of grep, sed and cut would surely be fun.

See above. Plus, "gen_acpi --dsdt" is not simpler than "gendsdt". If you 
really want to make this conform to your definition of simple, merge 
genacpi and gendsdt into iasl and be happy. Maybe merge flashrom and 
superiotool as well. Or merge superiotool into dtc.

Apologies for changing your argument from above, but it fits nicely:
Also, why should we merge them together? There's no advantage in doing 
that, it only needlessly increases the number of command line switches 
coreboot users are confronted with. Let's make it simpler for users 
rather than more confusing.
